Abstract
The invention is to provide a method for producing an aqueous resin dispersion capable of forming a coating film superior in adhesion to a polypropylene base material, and water resistance. Specifically, the invention provides a method for producing an aqueous resin dispersion, including a step of mixing and polymerizing a polyolefin dispersion (A), a radically polymerizable monomer (B), and a surfactant for emulsion polymerization (C), wherein the amount of the radically polymerizable monomer (B) mixed is 0.5 to 2 times the solid component of the polyolefin dispersion (A) in terms of parts by mass, and the amount of the solid component of the surfactant for emulsion polymerization (C) mixed is 0 to 3 parts by mass with respect to 100 parts by mass of the radically polymerizable monomer (B).
